感觉我脑洞太飘逸了...O(∩_∩)O哈哈~

坚决不重复造轮子、

 

AC代码：

 1 import java.util.Scanner;
 2 
 3 public class Main {
 4 
 5     public static void main(String[] args) {
 6         
 7         Scanner sc=new Scanner(System.in);
 8         int times=sc.nextInt();
 9         while(times-->0){
10             System.out.println(solve(sc.nextInt()));
11         }
12         
13     }
14     
15     public static int solve(int n){
16         return Integer.toBinaryString(n).replaceAll("0","").length();
17     }
18     
19 }
